GL(x) or Extension Class?

[Evil-Devil]

Hi, as I'm using some extensions I came to question what should I use.
The propriate Extension Class or the GL Class that implements the extension functions.

LIke ARB_TEXTURE_COMPRESSION and GL13. Are there any known issues like less performance or different implentation ways. Or is it just up to me to make sure I go one way and not mixing it up?

I don't think there should be any performance hit (someone can correct me on this). The only difference is if you use the GL13, that makes your program require version 1.3 of OpenGL versus just needing the specified extension.

Ah ok, thats good to known. I didn't know that the explicit call of GL13 requires GL 1.3 support by the end user.
Thx for fast reply
